Cleopatra Thea

Cleopatra Thea (, which means "Cleopatra the Goddess"; c. 164 – 121 BC) surnamed Eueteria (i.e., "good-harvest/fruitful season") was the ruler of the Hellenistic Seleucid Empire. She ruled Syria from 125 BC after the death of Demetrius II Nicator. She eventually ruled in co-regency with her son Antiochus VIII Grypus, who poisoned her in 121 or 120 BC.
